2. Turbulent Boundary Layer Separation and Control
Abstract : Boundary layer separation is an unwanted phenomenon in most technical applications, as for instance on airplane wings, ground vehicles and in internal flow systems. If separation occurs, it causes loss of lift, higher drag and energy losses. It is thus essential to develop methods to eliminate or delay separation. READ MORE

3. An experimental investigation of disturbance growth in boundary layer flows
Abstract : This thesis deals with the early stages of transition to turbulence in two different baseflows, namely the Falkner-Skan-Cooke boundary layer (FSC) and the asymptotic suction boundary layer (ASBL). Grid-generated turbulence is studied in order to characterise the isotropy levels, free-stream turbulence levels and characteristic length scales that will be present in the receptivity study.

4. Strain-assisted corrosion cracking and growth rate inhibitors
Abstract : A model for evolution of cracks as a result of strain-assisted corrosion is presented. The considered cracks possess a realistic geometry, where the tip region is an integral part of the crack surface instead of being a singular point. This geometry is either implicitly defined or is a consequence of crack nucleation from surface irregularities. READ MORE

5. Development of Transmission Electron Microscopy Techniques for the Study of Thin Films
Abstract : Transmission electron microscopy (TEM) is an invaluable tool for the study of the physics and materials properties of thin films. This thesis addresses innovations and novel applications of TEM to materials physics, and consists of three parts: the examination and development of innovative TEM sample preparation techniques, conventional selected area electron diffraction with new techniques for data extraction, and an extended TEM investigation of quantum dots.
